I was 14 when Pearl Jam's 3rd album was released on December 6, 1994. While at at the music store getting my copy on release day, I also stopped into Electronics Boutique and bought the two-disk Doom Shareware. I couldn't get home fast enough!
My Creative Labs 1x cartridge-loading CD-ROM used a TSR driver. You could put the disc in the drive, then use a command-line CD player program to play the music from the disc while in DOS...or in DOS games. I fired up the new album, and began the installation of Doom. Once the game was installed, I turned the in-game music levels all the way down and Vitalogy became my soundtrack for slaying demons and exploring endless corridors. Later, I even wrote a batch file to start the CD playing before starting the game.
I don't know how many hours I spent playing that game the first time, or how many times the album played through, but I remember vividly still seeing the hallways flying by my peripheral vision when laid down and closed my eyes. It was incredible.
I still have the box the shareware came in, but I think the disks themselves have degraded to where they're unusable. I also still have the boxes for D!Zone 150 and Ultimate Doom. For many years now, I've had zDoom and the Doomsday Engine both installed, and I typically play through all 4 episodes when I'm off for Christmas. I have since enjoyed the game's original soundtrack frequently, but from time to time, I still launch WinAmp with the PJ album on repeat before getting into the game.
